I think he didn't like Dexter because of the connection him and Gina claimed to have. He even said Dexter coached her or something like that. He always said that together they were evil, and it just sounded like he was jealous of the connection they had. He would have got with Charlie if he wanted to. The night he defended Charlie because Dexter didn't sit beside her, Charlie had just told him that Dexter told Gina if she didn't have a boyfriend he would have liked to be with her. That seem to fuel the fire even more.

Now I do think for day one Charlie liked Sam. I think she liked him from the first day, then Callum liked her and it was hard for her to jump that wagon.
